Leslie wore an Elie Saab bridal gown on her special day, which featured a long sleeved tulle gown with a soft mermaid silhouette.

The gorgeous dress, which is from the SS18 bridal collection and worth around $20,000, had an elegant illusion neckline and open back, which was fully embroidered with silk threads and a signature belt at the waist.

The couple met in 2012 while filming the epic fantasy series, playing tragic lovers Jon Snow and Ygritte.

Last year they announced their engagement, along with the wedding date.
